TO WHOM IT MAY CONCERN:

Be it known that I, FRANKLIN P. BSH, of Cincinnati, Hamilton county, Ohio, .have invented a new and useful Improvement in Mash-Coolers; and I hereby declare the following to be a full, clear, and exact desc'iiption thereof, reference being had to the' accompanying drawings, making part of this specification. i

My invention consists in the provision of one or more coils4 of cold-water pipes, which are caused to rotate within the mash-tub or tun, so as to both stir and cool the mash, said coils` discharging their heated water into a central well or waste-way.

Figure 1 is an axial section of a mash-tun provided with my improvement.

Figure 2 is a perspective view of the rotary coil.

A represents themash-tun or tub. Band C are concentric cylinders which, rising from the tub-bottom at its centre, enclose between them an annular well or waste-way, D. E is a shaft, which rises through the tubbottom at the precise centre thereof, and is rotated by gearing F, or other suitable means. The shaft E is surmounted by a pipe, G, which revolves within, and terminates in astuing-box, H, which receives the discharging end of a stationary cold-water pipe, I. Extending horizontally from the pipe G are .two or more branches J, bent into the represented coiled form, and discharginginto the well D. K are discharge pipes leading from the bottom of the well D. L are rakesattached to the revolving pipe G, and having fingers l, which, being situated immediately -in front of the vertical portions of the coils, serve to protect the latter, and to thoroughly stir and agitate the mass, so as to constantly bring frlesh portions iu contact with the coil.

I claim herein as new and of my inventionl 1. The arrangement of tun A, central annular waste-way D, rotary centrally4 discharging coils J, central supply pipes Gr I, stuing-box H, and rake L, for the purpose set forth.

2. In the described combination the rotary coils J, discharging into a central waste-w'ay, D, in the manner set forth. l v

`In testimony of which invention I hereunto set my hand.

FRANKLIN P. BUSH.
